FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 309,545, dated December23, 1884:.

Application filed February 15. 1584. (Nomodet) To all whom it mayconcern:

Be it known that I, OTTO HIRT, of Carlsbad, in the Austro-HungarianEmpire, have inventeda new and useful Improvement in Saving Apparatus inDanger by Fire, of which the following is specification.

Thisinvention relates to tircescapes of the endless-belt variety; and itconsists in the construetion and combination ofparts hereinafter setforth and claimed. 7

In the accompanying drawings, Figure 1 represents a side view of asuspending device for the endless escape-belt. Fig. 2 represents a planview of the same. Fig. 3 represents a detail view (from below) of thehook which forms part of such device. Fig. 4 represents a verticalsection on the line I I I of Fig. 1. Fig. 5 represents a modificationot' the suspending device. Fig. 6 represents a detail side view of thesuspending pulley and its frame. Fig. 7 represents a front view of thesame. Fig. 8 represents a view similar to Fig. 7, the hinged part of theframe being open. Fig. 9 represents a detailed front view of the belt tobe worn by the person to be saved, and Fig. 10 represents averticalsection through the entire apparatus as attached to the wall of abuilding.

The present apparatus consists in an iron hook, A, Figs. 1, 2, and 3, inboth back legs of which, a c, is.a strong screwspindle, b b. A third legor brace of the hook A can be shortened orlengthcned, according to thewall of the building, by means of the movable part c, hinged thereto and't'ormingthe tip thereof. The two back legs, a u, are set into tubularsocketcd bracketarms 7; 7.:, provided with the screw-spindles b b, andare fixed to slide backward and forward and can be held firm in thedesired position by the boltf. A hook (represented in Fig. 5) which isbuilt into the masonry above the highest iloor of the building can alsobe used. In such a case hook A serves also to trice up scaffoldings forplasterblock, as shown in Fig. 10.

ing or painting a building. \Vhen hook A is fastened, then a block, B,Figs. 6, 7, and S, is hung onto it and a rope runs through the At adistance of one-half or a whole meter thimbles g are warped into therope, and into them the person to be saved hangs the snap-hook h, Fig.9, of his belt. Such belts in adequate number accompany the apparatusdescribed, and are furnished in case of danger by the firemen. Thesaving is performed then in the simple Imannerdescribed-thatthepersonsin question lhang themselves onto the ropekept in the ,l middle of the window. 1l the rope is performed by l Thehoisting up of one man of the tirebrigade.

Ihe peculiar advantages of this apparatus are increased by the fact thatthe saving of people can be performed from all floors of a 1 house atthe same time, and, further, that the managementof such a savingapparatus requires no previous instruction or practice, so that anyuninitiated person can be instru mental in the saving of life by meansofit.

What I claim is- 1. An adj ust-able hook vided with a leg or brace, 0,having a hinge l part, c, substantially as and for the purpose I setforth.

2. The tubular brackets 7e 7:, in combina tion with the legs a a ofbifurcated hook A, and the fastening-bolt f, substantially as set forth.

The combination ot'screws I) b with the sockcted tubular brackets 7c 7a,the hook A, adjustable therein, and the pulley and endl less belt,substantially as set forth.

I testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

OTTO HIRT.
